Switching spin states in manganese ions with light opens new path for molecular memory‎

Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular materials, which require very low temperatures—ranging from 100 to a maximum of 130 Kelvin (minus 173 to minus 143°C)—making their application significantly more difficult.
